" s Claims." (o1. la-'18) My invention relates to vulcanizer4 adapters,

* and more. particularly to an adapter that L will conform to tires of various sizes, within predetermined limits.

An important object of my invention is to provide such an adapter that will not make a rib or ridge on the tire at the edge of the bead plate.

Another object is to provide shoulder plates and bead plate extensions that telescope the one with the other. v

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in thecourseof the following description.

` In the drawing, like reference characters designate'similar parts in the several views.

' Figure 1 is a vertical section through a vulcanizer in which is shown a cross section of an embodiment of my invention.

Figure 2 is a broken perspective of a part of movable walls provide engaging means for a cross bar I3.` A clampbolt I4 is adjustable in the `cross bar. A clamping plate I5 has a-ball and socket connection I6 with the foot of the bolt I4. Thus far is construction substantially as shown in kmy Patent No. 2,064,416, issued to me on December 15, 1936.

f The present invention comprises a tread plate I1, having a curved portion I8 and ilatedge porvtions I9. The curved portion I8 is a matrix for the tread oi the tire and may be machined out, in any desired pattern.` Shoulder plates are slidable up and downvthe flat portions I9 rat y either side of the tread plate I1. The'shoulder plates have depending anges 2I. Pins 22, screwed into the flanges 2|, slide in alined recesses 24 in the tread plate I1, directing the movement of the shoulder plates 20. v

`Set screws 23 on the tread plate limit such movement, while coiled springs 25 in the recesses 24 urge the shoulderplates outwardly with regard to Vthe treadv plate I'I. The shoulder plates 20 have offsets 21 providing shoulders 26 on their outer faces.

`Bead plates 28 and 28 are provided normally above theshoulder plates. Pins 30 are xed on the bead plate 28 as by a driving fit, and slide in alined recesses 3| in the bead plate 29. Coiled springs 32 in the recesses 3l urge the bead plates apart when under tension, and set screws 33 limit relative movement of the bead plates.

The bead plates 28 and 29 have depending flanges 34 and 35 respectively, which slide on the shoulders 26 of the shoulder plates. Abutting edges of the flanges 34, 35 and offsets 2l are inclined, as shown at 36.

In the use of my present invention, the tread kplate Il and shoulder plates 2D are inserted in plates are then placed on the beads of the tire, vas shown in 'Figure 1, with the flanges 34, 35

depending at either side of the tire and disposed on the shoulders 26.

After the cross bar I3, the bolt I4 and the clamping plate I5 are positioned on the bead plates, the movable wall 5 is forced toward the stationary wall 5, compressing my shoulder andk bead plates tightly against ythe sides of the tire. The air bag 39 is inilated and heat applied to the mold as usual. Due to the integral naturey of theflanges 34, 35 and the bead plates 28, 29, no ridge or rib of rubber is formed on the tire at the junctions ofthe bead plates and said flanges.

SaidI compression of the adapter plates places tension inthe springs 25 and 32, whereby the adapter bead plates and the adapter shoulder plates are moved apart when the movable wall 6 and clamping plate I5 are released, thereby releasing the tire after vulcanization.

It is believed apparent that the present adapt-- lers easily conform not only with tires of differentwidths,v but Ialso with ltires of differentv depths. The flanges 34, 35 are free to slide up and down upon theshoulders 26, which affords the adjustment .for tires of dilierent depths. 4

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the. spirit of 'my invention. l, therefore, do not wish to restrict myself to the particular form of construction' illustrated and described, but desire to avail myself of all modifications which may fall within the scope ofthe appended claims.

of a tire in said position, and integral flanges on the bead plates having sliding engagement with another portion of said offset outer faces, the outer faces of the flanges and the outer faces of said first-mentioned portion of the offset faces being substantially in alinement to present substantially flat faces to the Walls of the vulcanizer.

2. Vulcanizer adapter means comprising a;

tread plate having inclined sliding surfaces, a shoulder plate slidable on each of said surfaces at either side of the tread plate, the shoulder plates having shoulders on outer faces With regard to a tire in the adapter means, bead plates arranged to engage Athe beads of a tire in said the offset portion of theouter faces of the shoulposition, andanges kon the bead plates having "i slidingengagement with the outerl faces of the shoulder plates and being limited in one direction by the shoulders on vthe latter plates, the

shoulders being so arranged that when the flanges 'engage said shoulders the bead .plates are lifted by theshoulder plates sliding up the inclines on the tread plate. 3. Vulcanizer adapter means comprising a tread plate, a shoulder plate slidable on the treadV plate at either side thereof, the shouldervplates having inner faces for engaging the shoulders of a tire placed inthe adapterl means, anges on the shoulder plates, pins on the flanges and the tread plate to direct the sliding movement of 'the shoulder plates relative to the tread plate, portionsof the outer faces of the shoulder plates being offset with regard tothe outer faces of n the flanges, bead plates arranged to engage the beads of a. tire in said position, and flanges on the` bead plates having sliding engagement kWith der plates.
